Whenever I use the Catalyst Control Centre to change the GPU, nothing changes after reboot. In fact, when I do the fglrxinfo command the terminal only reports seeing one GPU, the integrated one (HD 4250).

The dedicated one (Mobility HD5470) goes unnoticed and I can't seem to use that GPU at all. I really don't want to use the Open Source drivers because I've found there generally slower than the proprietary, but the proprietary doesn't seem to work either.

By the way, I'm running AMD/Intel hybrid graphics and when i run fglrxinfo I only see the AMD too nevertheless I can see both on the Catalyst Control Center so that might not be an error.
